Objet : [mg96586] Select All Lists Where Any Element is a Given Value
Hello everyone,
Suppose I have the list
X = {{1, 2, 3}, {8, NA, 20}, {-7, 9, NA}},
where NA is a string, although it need not be. How can I use Select
to pull out all lists in X where NA appears in any element? In this
example, I want to pull out the second and third list.
Regards,
Gregory
